Do Not Disturb on Your Terms: The standard Do Not Disturb mode is great for silencing notifications during sleep or meetings. However, most smartphones allow you to create custom schedules for Do Not Disturb. This means you can silence calls and notifications during specific times of the day, while allowing important contacts or apps to bypass the restrictions. Imagine getting a good night's sleep without work emails interrupting your dreams, or focusing on a presentation without social media distractions.
Gesture Navigation and Shortcuts: Many users navigate their phones with the traditional on-screen buttons. But modern devices offer a more intuitive and efficient way to interact – gesture controls. These allow you to perform actions like swiping back, opening apps, or taking screenshots with simple gestures on the screen. Mastering these gestures can significantly speed up your workflow and make using your phone a more fluid experience. Additionally, some phones allow you to create custom shortcuts for frequently used actions. For example, a double-tap on the power button could launch your camera app, or a three-finger swipe could open your favorite music player.
Hidden Developer Options: For the tech-savvy user, most Android phones offer a hidden menu called Developer Options. This menu unlocks a variety of advanced settings, allowing you to customize animations, enable USB debugging for app development, or even increase processing power (with caution!). While some of these options are best left untouched by casual users, exploring Developer Options can provide a deeper understanding of your phone's inner workings and unlock functionalities for power users.
Pro Mode Photography: Move beyond auto mode and unleash your inner photographer with Pro Mode. This mode gives you granular control over settings like ISO, shutter speed, and white balance. Experimenting with these settings allows you to capture stunning photos with professional-looking effects.
Manual Focus and Exposure: For even more control, delve into manual focus and exposure settings. Manual focus allows you to choose the specific point you want the camera to focus on, while manual exposure lets you control the amount of light captured in the image. Mastering these settings allows you to achieve creative effects and capture photos that stand out from the crowd.
Hidden Camera Modes: Many phones come with pre-loaded camera modes that cater to specific situations.

Split-Screen Multitasking: Juggling multiple tasks on your phone? Android's split-screen multitasking feature allows you to utilize the large screen real estate effectively.

This enables you to reply to emails while browsing the web or check social media updates while working on a document.
Guest Mode: Sharing your phone with a friend or family member but want to keep your personal data safe? Enable Guest Mode. This creates a temporary profile with limited access to your apps and files, ensuring your privacy remains intact.

Unearthing these easter eggs can be a fun way to discover hidden aspects of your phone and add a touch of whimsy to your user experience.
Back Tap Feature: For a touch of accessibility and convenience, iPhones offer a Back Tap feature.

This can significantly streamline your workflow and make frequently used actions a breeze to perform.

This overlay provides quick access to various functions, making navigation easier. Furthermore, the Shortcuts app allows you to automate workflows and create powerful one-tap actions for frequently performed tasks.
Screen Pinning: Android's screen pinning feature allows you to lock your phone onto a single app. This is useful when handing your phone to someone else, ensuring they can't access other apps or your personal data.
Find My Device/iPhone: Both operating systems offer built-in features to locate your lost or stolen phone. These features allow you to remotely locate your device, play a sound, or even erase all data to protect your privacy in case of theft.

Explore your phone's settings: Dedicating some time to exploring the various menus and settings within your phone can reveal hidden options and functionalities you might not have noticed before.
ADB (Android Debug Bridge): For developers and those comfortable with tinkering, ADB unlocks a powerful suite of tools for advanced phone management. This allows you to connect your phone to your computer and perform actions like sideloading apps (installing apps from outside the Google Play Store), backing up data, or even tweaking system settings inaccessible through the standard interface. Use ADB with caution as improper commands can potentially harm your device.
Custom ROMs and Kernels: For the truly adventurous, the world of custom ROMs and kernels awaits. These are modified versions of the Android operating system that offer a plethora of customizations and features not found on stock ROMs. However, installing custom ROMs can be a complex process and carries the risk of bricking your phone (rendering it unusable). Only attempt this if you're comfortable with the technical aspects and potential risks.
Hidden System Apps: Many Android phones come with pre-installed system apps that are hidden from the app drawer. These apps often handle core functionalities or diagnostics and can sometimes be accessed through hidden menus or file explorer apps. Be cautious when interacting with these apps, as modifying them can lead to unexpected behavior.
Voice Control: While Siri is a familiar voice assistant, iOS offers a more in-depth voice control feature. This allows you to control almost any aspect of your phone using your voice, from opening apps and composing emails to navigating menus and adjusting settings. This can be a powerful tool for accessibility or hands-free usage.
Guided Access: This hidden feature in iOS restricts your phone to a single app, ideal for situations where you want to hand your phone to someone and prevent them from accessing other apps or data. This is useful for children playing games or showing someone a specific app without the risk of them exploring other parts of your phone.
Hidden Diagnostics Codes: Similar to Android's secret codes, some iPhone models have hidden diagnostic codes that can be accessed through the phone dialer. These codes can reveal information about your phone's hardware, network connectivity, or even battery health. Use these codes with caution as some might alter settings or access sensitive data.
